' useful Improvements in Hose-Couplings of in the State of Indiana, have invented new and.

which the following is a full, clear, and complete expositiomsuch' as will enable others amiliar with'the art towhich this invention roerelates to make and use the same.

. m anufacture'a hose couplin provision of a hoseunsightl My fpresent invention, broadly-speaking, 'hasire erence to anew and useful article of.

for expeditiou'sly connecting the ends of ose or pipes, whereby aplurality of sections may be joined together to provide an aqueduct of the desired len th.v p c One 0 the objects I have in view. is the rubber hose, whereby the general contour of the hose will joints, but will present a uni ormly neat an mechanically perfect appearance.

A further objectis to rovide a hoseecoupling which will be simp e tive in actionand adjustment, easily connected and disconnected, "andwhich can be made and sold at a comparatively low-price.

A still further object 7 new article of manufacture a hose-coupling videa simple and 1 necting and forming Water-tight joints in es, which may be easily.

of the particularly intended for connecting the abutting ends of rubber hose, butwhich may also be employed for uniting theends of lead pipe or for'uniting pipes or the like of other materials, and, finally, a further. object isto pro-.

practical coupling for confiuid-transmitting pi and quickly manlpu ated withouttheuse of tools and. which will not mar the uniformity ipeor impede the flow of fluids therethrougli. p Otherv objects and advantages of this invention will be made apparent in the course an inspection ofthe accompanying rawings.

This invention consists particularly in a hose couplin embodying new and useful features and etails of construction and the relative disposition of the various contributing elements, substantially as herein shown and described.

. The preferred manner for the construction central section taken through all -t coupling adapted for g operations as briefly quickly and securely connecting the ends of not be disturbedby lar e and in character, posiis the provision of a stantially' as shown. v of the flange 1 should rise somewhat from t e Patented m1. 27, 1966."

' of my invention is shown most clearly in the accompanying drawings, in -which.-

Figure 1 is an end view of myinvention. Fig. 2 is a side elevation of the essential part ofmy invention detached. Fig. 3 is a side elevation showing my invention as employed in its intended purpose of connecting. the abutting ends of two sectionsof hose or pipes, and Fig. 4 is a vertical lo "tudinal shown in Fig. 3 and providing an introspective view of the invention. v

I In the drawings similar indices denote and refer to like parts throughout the several views. -l

Referring now to the drawings in' detail, I

. will take up the description of my invention e parts and will describe the various parts and their may. I

My invention consists, essentially, of the integral core,(shown in full in Fig. 2,.) and it COIISISlJ S of the respective rightand left hand nipples 2 and 3, which are integrally cone,

nected by the central flange "1.

r The nipples 2' and 3 are identical in form, and construction, each being cylindrical, with the greater portion of theirperipheries longitudinal, parallel with the. axial line of t e core, and then swelling slightly'outward andconnectingwith the ange 1 at an angle, substantially as shown. Commencing at their outer termini the peripheries of the nipples have formed therearound a number of convolutions of spiral grooves or V-threads a and b, "respectively, which threads extend over said swelled'portions-of the nipples to or near the respective sides of the flange 1, sub- The peripherical ed e plane of the peripheries of the nipples 2 and 3, and this edge'of the flange may be formed circular in, contour, with its peripheral ed e na which will provide a gripping-surface either for the hand or for a wrench, ifrequired.

and "compactly as I knurled, if desired; but I prefer toformt e v Jed e polygonal, or more particularly hexago IOO (designated by the letter 0,) which forms the passage-way for the fluid which may pass therethrough when the hose are connected.

The letters A and B denote and left sections, respectively, of the hose each the right connected by my invention. Each of said sections of hose has a central bore, as and 2, respectively, extending in an axial .(llIGCtlOIl ther'ethrough.

The numerals 4 and 5 denote right and left thimbles, which are'placed around the pespaces y and z, res ectively, of the res ective I hose A and B, an then by turningt e core or by revolving the hose the end portions of the hose may be caused to travel on the threads of the nipples, thus drawing the ends of the hose near to or in contactwith the sides of the flange 1, substantially as shown, and'by reason 0 the threads ti htly entering the interior and contacting wit the interior I walls of the hose, and, further, by reason of the outer Walls of the hose being unable to expand by reason of the respective thimbles, it Will be apparent that thehose will be very tightly held in place by the threads, and thus forming a point or union of great strength and also providing a waterproof joint of greater resistance than is the resistance of the hose intermediate of or at a distance from one of the joints thus formed.

It is apparent that the thimbles 4 and 5 may, if desired, be dispensed with entirely, yet by their employment the joint is rendered stronger and absolutely impervious to the water-pressure.

From the above it will be seen that by the construction shown and described I have accomplished the objects otherwhere referred to in this-specification.

My improvements are perfectly adapted to accomplish the resultsand objects stated, and it is evident that chan es in and modifications of the construction erein shown and described may be made and that analogous parts may be used to accomplish the same results without departing from the spirit of my invention or sacrificing any of its many advantages.

It will be observed that the core is tubular and preferably strictly cylindrical in its interior form, but composed externally of the middle prismatic annular operating flange or shoulder where its diameter is greatest, a pair of reverselytapering and reverselyscrew-threaded cones and cylindrical extensions of the same having the screw-threads thereof extended to their ends. The thimble's or ferrules 4 and 5 do not at all impede the enga ement of this core with thehosesections, int hold thematerial of the ends of said sections in engagement with the screwthreads and prevent it from bulging outward beside protecting it and guarding against the dislodgment of the core. They also permit ready access of a wrench or spanner to the peripheral part of the said flange or shoulder, which is located in a suflicient s ace between them, with its angles exten ing outward slightly beyond them. The core is preferably of a single casting, but of course might be made in several pieces securely joined. The conical form of the parts of the inner core nearest the shoulder facilitates turning the core in to tighten the joint, also turning reversely to uncouple. The ferrules make this construction feasible. The arts of'the core beyond the ferrules bein cy indrical will not require such aid, since t ey do not press the hose material outward. Having no ta er, they will hold more securely than woul be possible for uninclosed expansible tubular ose material.

Having now fully shown and described my invention and the best mode for its construction and use to me known at this time, what I claim as new, and desire to secure by Letters Patent of the United States, is

1. An integral tubular cou ling-core for hose-sections having external y the form of two reversed cones terminating in cylindrical extensions and connected by an intervening prismatic annular flange or shoulder of greater diameter than the bases of said cones, these cones and their cylindrical extensions being screw-threaded in opposite directions to each other substantially as set forth.

2. A air of hose-sections provided with termina protecting and binding ferrules open at the end, in combination with a tubular coupling-core screw-threaded from near its middle in opposite directions, consistin of two reversed cones, their extensions and intermediate means for facilitating the turning of the said core substantially as set forth.

- In testimony whereof I have hereunto signed my name to this specification in the presence of two subscribin witnesses.
